T 0 all whom it may concern: I

Be it known that I, FRED G. DicKERsoN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in (JamFilling Machines, of which the following is a specification.

My invention relates to machines for filling cans, bottles and other vessels with. liquid, such as condensed milk, mixed paints, oils, and other commercial products for which such vessels or receptacles are used, and the terms can and cans are herein used as representative of the various kinds of vessels or receptacles used for liquid and semi-liquid commodities, and the terms liquid, liquids and milk as representative of such products orlzommodities. -()ne of the objects of my invention is to provide an improved machine of this character which will be simple, durable and reliable in construction, and effective and eflicient .in operation.

A further object of my invention is to provide an improved can filling machine which \villautomat-ically fill the cans presented to .it from a source of suppl at a rapid and uniform rate consistent with the character of the cans and liquids for which the machine is used, and will discharge the filled cans in such manner that'if desired they may be directly fed or presented to other machines, such as sealing machines.

A further object of my invention is to provide an improved can filling machine which will be continuous in operation and avill handle a large number of cans in process of filling.

A further object of my invention is to provide an improved filling machine which will automatically measure and charge or. inject the liquid into each can or vessel with extreme and uniform accuracy, and which will leave the vessel in such condition that the liquid will not interfere with the sealing operation. r

A further object of my invention is to provide an improved unit or individual measuring and filling mechanism which will automatically measure a charge of li uid for a SlK'CBQdlIlg'I can or group of cans w ile filling a present can or group thereof with a pre-measured charge.

A further object ofmy invention is to 'cleaning'the parts, particularly those and passages through which the liquid provide an improved can fillin machine parts passes, whereby the machine maybe kept in a sanitary condition, especially when used in handling condensed milk and cream, or such food products which must necessarily be cleanly handled. f

A still further object of my invention is to provide an improved can filling machine which will charge or inject the liquid into the -cans or vessels in such manner that it will not foam.

A still further object of my invention is to' provide an improved can filling machine which can be readily regulated and adjusted for filling cans of various sizes, such as are used for commercially marketed quantities of liquid commodities. Other objects of my invention will hereafter appear.

The above and other new and useful ob- 4 jects hereinafter appearing are accomplished by, and my invention consists in,

the construction, combination andarrangement of the parts herein described and shown in the accompanying drawings, which illustrate one exemplification of my invention, and more particularly pointed out in the appended claims.

Fig. 11 is a vertical section of the upper portion of the unit measuring mechanism modified as more carefully explained herecondensed milk or cream, cans of this character usually being provided with a central opening in one end through which the milk is injected, and which is afterward hermetically sealed, and I will describe my invention with reference to the machine shown rately, for instance the unit measuring and and used for this purpose; but it willbe understood, however, by one skilled in the art after having obtained an understanding of my invention from the. disclosures herein made, that my invention is equally as capable of being embodied inor applied to machines for handling other liquid or semiliquid products or commodities and the v rious types of vessels used therefor. It wi l likewise be understood that the several combinations' and arrangements of parts the functions of which are more fully explained hereafter, may be employed in other filling machines, either in their entirety or sepafilling mechanisms may be employed in connection with other means for presenting the cans to and removing them from said mechanisms; all without departing from the spirit and scope of my invention.

"The machine shown in the drawings has a frame or bench composed principally of a suitably'formed flat bed A, supported at a convenient height for the operator, upon legs or standards A Upstanding from this in a suitable bearing A 'is a vertical main shaft A which constitutes the axis for various rotary parts of the'machine, as hereinafter explained. At one side of the bench or table 'A is a standard A which supports a can feeding chute 1, by which the cans C are fed or guided to the machine. This chute may lead from the source of supply of cans, such as a can forming machine 10- cated on the floor above or in any other place-best adapted to operating conditions. The chute may be made of theproper form to accommodate the particular type of cans or vessels which the machine is intended to handle. In the drawlngs the chute is formed as an open work structure, so that the operator may observe the movement of the cans at any time. At a convenient point in the chute there may be provided a bail or yoke member 2, pivoted at3, and having a curved tongue 4:, adapted when the bail is dropped to the dotted position (Fig. 1) to be interposed in the path of the cans through the chute and stop the feeding of the cans. This stop member maybe normally held in its upper or non-stopping position by means of a stirrup or latch 5, pivoted on the chute at 6 and having an extension 7 for tripping it when desired. This mechanism obviously may be operated by hand, or it may be operated automatically in the event that anything goes wrong with the machine. The lower portion 1 of the chute curves horizontally and this portion of its walls 8 '(Figs. 1 and 2) are given aquarter turn or twist. The purpose of thisarrangement 1s to feed the cans, which come own the chute in a horizontal position, to the machine on end or in an upright position. The construction of these parts, however, is determined by operating and manufacturing conditions and by the character of the vessels to be filled. The inner. end 9 of the chute lies close to the periphery of a horizontal rotary conveyer or carriage B mounted upon the central shaft A This rotary carriage has a plurality of semi-circular cells or pockets 10 formed in and equally siaced around its periphery which successively re 'ceive the end cans ofthe series in the chute as'the carriage rotates, the cans being fed in preferably by the Weight or pressure of the series of cans in the chute. As each can C is fed into its cell, it is carried thereby upon a rotary table E disposed below the carriage B in the direction of the arrow (Fig. 2). --As it leaves the chute it is engaged by a series of peculiarly formed springs D, which ress upon the several adjacent cans and rmly and positively seat them in their'respective cells during a portion of the arc in. which they travel; Referring more particularly to Figs. 1, 2, 5 and 5, it will be noted that this series of springs is composed of several (preferably three) individual spring members, made of spring rod or wire and bent into the pecul viar flattened S-shape like-that shown more particularly in Figs; '5 and 5, iving them the proper resiliency. Each sprmg has two eyelet ends 12, which are bolted in a row upon a standard or supporting member 13 upstanding from the bench or table A of the machine. These springs have curved U- next preceding cans.

presses whichever can or cans happen to be in engagement with it at any instant. In this manner the can which enga es the first spring 14 of the series after caving the chute cannot effect the other springs, and relieve the pressure exerted thereby upon the however, the several cans which are engaged by the springs are all. properly and uniformly held seated in their respective cells or pockets.

The cans after leavin with the carriage B an lower or feeding level, which is formed by the surface of the table E, the table being of a diameter suflicient to sup ort the cans on endf Before leavingthe ast end 15 of the series of, spring members D, the cans successivel ride up a cam or incline 16 (Figs. 3 an 5) to a higher or elevated level 17, which I term for convenience a filling level. This latter level is formed by the upper surface of a stationary platform L, which embraces the peripheral por-' tion of the table E, which continues around through about three-quarters of the circumference thereof. The platform is mounted upon several threaded studs L upstanding. ,from the table A and screwing into the lugs P for the purpose of raising and lowerln the latform to accurately regulate the lling evel 17. At about the point H the filling level 17 terminates in a drop or incline 18 (Fig. 4'), down which the cans successively rlde upon the rotary table la. After riding down this incline to the lower level the cans may be taken from the machine in any desired manner. In the drawings, however, I have illustrated a portion of a horizontally disposed rota table G (Figs. 2 and 4), the surface -0 which is coincident with that of thetable' E. This table G represents a can carrying member or feeder fora sealing or capping machine.

At the same time,

the chute travel table E a certain distance at what I term, for convenience, a"

the point H in their travel, they are successively shunted off or deflected from the table E and conveyer B onto the rotary table G. This may be accomplished by means of a simple curved deflector bar or rail 22,

the end 23 of which is positioned in the path of the moving cans 2). In order that the cans may be maintained in the same successive relation as they leave the table, they are received in an annular series of cells or pockets which are formed by a plurality of upstanding pins 2 1 on the rotary table G. As it is essential that the cells of the rotary member B and those of the table G properly register during rotation inv order that the cans may be properly transferred, 1 have arranged the parts so that the rotary table drives the conveyer B through the medium of an adjustable connection. Thus, in Fig. 2 it is. observed that the rotary table E has two upstanding lugs or arms 31, positionedon opposite sides of one of the spokes 32 of the carriage B and spaced sufficiently apart to allow some play for the spoke between them. An adjusting bolt 33 is screwed horizontally through each of these arms into engagement with the' spoke 32. Hence by manipulating these opposed bolts the rotary carriage B magibe I rotated relatively to therotary table sufficient amount to properly time or register its can cells with those of the rotary table G. At the same time this arrangetravel with the table G as is necessary. A

suitable guard 26 mounted upon a standard 27 upstanding from the bench A may be provided for preventing the displacement of the cans as they ride down the incline 18, and for assisting the deflector bar 22in properly transferrin the cans to their cells by the'rota table The machine i1 ustrated in the drawings. as before stated, is designed for handling condensed milk cans of a type provided with comparatively small filling openings or apertures O in the center of one head or end 0 (Fig. 12); The fillin nozzles N are constructed accordingly. of elevating the cans to 'the filling level, as before described, is to bring them into filling relation with the nozzles N, but this may be accomplished of'course by lowering or moving the nozzles relatively to the cans. 'These nozzles are arran ed in an annular series and are individua to the cells 10 of the rotary carriage B.- They are removably mounted upon the ends of short tubes 30, and are centrally positioned'above the cells 10, the tubes 30 being removably mounted vertically in suitable bearings or bosses 43 he purpose formed in'an annular overhanging flange or rim M, preferably cast integral with the rotary conveyer B. The nozzles N arepreferably made in the form of caps of rubber or other suitable material removably fitted on the lower ends of the tubes 30 to permit their removal for cleaning purposes.

The lower ends of these caps contact with the upper heads or tops of the cans as the cans are elevated. They have a number of radial depressions or air outlets 35. In the lower portions of the caps small metallic plugs 36 are inserted, having central pasthe space formed by virtue of the differ ence in diameter between the can opening O and the tips 38. From thence the displaced air escapes through the outlets 35 to I the atmosphere, and the parts are so proportioned that the displaced air may escape as fast as it is displaced. In order to cause the liquid to leave the nozzles in a direct compact stream and prevent foaming insthe cans, I provide each tube with a member 40.

This member is loosely inserted in the end of the tube and is of sufiicient length for the purpose. As shown in the drawings, it may be made of a thin piece or pieces of metal disposed at right angles and forming a cross in section, as shown in Fig. 14. These members virtually form a plurality of longitudinal partitions in the tubes, and their effect is to split or divide the flow of liquid through the tubes 30 into aeorrespond ing number of direct smaller streams. This prevents the tendency of the milk or liquid to whirl within the tubes and nozzle passages, As the streams of milk leave the ends of the tubes 30 they-combine or unite again in the passages 37 of the filling nozzles-just prior to leaving the tips 38, and the upper portions of the passages 37 are enlarged to form mixing chambers, so to speak, for this purpose.

In the machine shown in the drawings I .provide a number of measuring and filling mechanisms, the function of which is to control the quantity of milk which goes into the cans-through the nozzles. I prefer to useone-oftliese mechanisms per can to be filled,

but I may, under certain conditions, ar-

e I range" the structure so that each may control the filling of a number or group of cans.

;These mechanisms may be rotated 'or moved in any desired manner on the machine according tothe particular conditions and requirements which the machine is desi ed to meet. In this machine I arrange t em in an annular series. Figs. 1 and 2 showseveral of these units, the rest being omitted forthe sake of clearness. They are positioned immediately above the can cells of the rotary conveyer B, in order that the milk after it leaves these mechanisms may pass by the most direct and shortest paths to the cans, the reasons for which will hereinafter appear. The simplest method of mounting these mechanisms is to secure them to the upper ends of the tubes 30 in such manner that each tube 30 may be removed with its controlling mechanism. At the point where the tubes 30 join the body of the measuring and filling mechanisms, provide shoulders (3 which rest upon the bearing bosses 43 so that the tubes 30 and the nozzles N will project the given distance below the rim or flange M of the rotary carriage B. Each of these measuring and filling units P is made in the form of an elongatedhollow cylindrical body casting open at its top and having a sufficient quantity of metal at its bottom to accommodate a reverser. In order that the interior of the cylinders may be accessible for flushing and cleaning purposes the upper end thereof may be closed by means of a cap or cover member 51, Figs. 6 and 7, having an annular shoulder 52 fitting the upper edge or rim 53 of the cylinder. This centers the cap and provides a tight joint. In addition to this a gasket 54 may be interposed between the cap and cylinder as a further precaution against leakage. The cap 51 may be held in position in any suitable manner found best adapted for the purpose. I prefer, however, to use a curved clamp member or arm 55 hinged at one end in lugs 56 at the side of the cylinder. This arm bridges or spans the cap and engages an upstanding portion 57 for the purpose of tightly seating the, cap. The free end of the clamping arm 55 may be yoked or provided with an open ended slot 58 (Figs. 6, and 8) adapted to receive a bolt 59 which is hinged in lugs 60 on-the opposite side of the cylinder. The free end 61 of .this bolt may be threaded to receive a clamping nut 62 whereby sufficient clamping pressure may be obtained to hold the cap firmly in position. rangement provides a very convenient means of holding the cap in position and at the same time the cap may be readily removed whenever desired. The interior of each cylinder is divided or partitioned off, so to speak, into an upper and lower chamber, by means of a movable partition 65, which, as seen in the drawings, is fitted within the cylinderin such manner that it may freely move with the liquidand at the same time prevent any liquid from passing by it from one .compartment to the other and further acts as a valve in that it, at predetermined polnts in its movement, acts as a clgsure for It will be seen that this arthe means of communication to the compartments. I refer to make the movable partition in t e form of a cup having an annular side wall 65 and a flat bottom wall 65 for various reasons, one of which is to enable me to adjust the mechanism to different sizes ofcans, as will appear hereinafter. However, it may be made solid, if desired. At the lower end of its stroke or range of movement inthe cylinder, the mov- .able partition strikes the bottom wall 75 of the cylinder. The upper end of its range of movement may be determined by a vertical gage rod 66, as shown in Fig. 7, or by means of a central tube 67, as illustrated in Fig. 11. It will be seen that although this arrangement forms in effect two chambers in the cylinder, the capacity of these chambers varies in accordance with the particular position of the movable partition 65 within the cylinder. In other words, as the movable partition 65 moves upward, the up per chamber will gradually decrease in capacitv and the lower chamber will correspondingly increase in capacity, and vice versa. Itis b means of this arrangement that the mechanism exactly measures a quantity of liquid for a succeeding can, while charging liquid into or filling a pres ent can. In order that the quantity of liquid measured by each chamber may be regulated with extreme accuracy, I mount the gage 66 (Fig. 7) or the tube 67 (Fig.

11), as the case may be, in such manner that the may be longitudinally adjusted and set.

portion 57 of the cap member carries a threaded sleeve 68. provided with a lock nut 69, so that it may be vertically adjusted, as required. The gage 66 is confined against vertical movement in this sleeve b the shoulder 66 on its reduced upper en portion 66 anda lever or arm 70, the lever being removably fastened on the end of the gage rod, by means of a screw .70 This enables the gage 66 to *be rotated on its axis in any ositi'on at which it has been vertically a justed by mean s-..0;Lthe. threadedsleeve 68. g -suitabl mechanism other than thatju'st' described may be used to ac coi'fi'plish these results; for instance, as

' shown in Fig. 11, the tube 67 may bethread ;chamber or socket formed in the lower portion of the casting in suchmanner that it ed into the central portion of-the cap whereby it may be vertically adjusted, and it maiy have a lock nut 71 for setting it in its a iquid is supplied to the mechanism through a tube72, which enters the, lower portion of the cylindrical or body castingand terminates .in a port or assag'e 73, opening into communication wit a reverser member 74. This reverser member is seated in a may be rotated. It will noted that both {usted position. In the structure shown, the

cessible therefrom. The reverser has a round-ended, central projection 75 against which the dished-end 76 of a leaf spring 77" presses to maintain the reverser in its seat,

and at the same time allow it to be rotated. The pressure spring is pivoted on a boss 78 projecting from the cylinder so that it may be swung away from the reverser to permit the removal thereof. The upper end 79 of the spring engages the cylinder and provides a yieldin place. The reverser has two grooves or passages 80 and 81 formedon opposite sides thereof. These grooves or passages communicate with peripheral or annulargrooves 82 and 83, respectively, formed in the reverser member 7 4: and spaced apart thereon. As shown in Fig. 6, the inlet port 73 and the outlet port 84 leading to the tube 30, are so arranged that they communicate with the rotary reverser at diametrically opposite points in such manner that the grooves 80 and 81 register therewith. In other words, the groove 80, when the reverser is in the position shown in Fig. 6, registers with the inlet port 73 and connects that port with the annular groove 82, and the groove 81 connects the outlet port 84; with the groove 83. "When, however, the reverser is rotated a half turn, these conditions are reversed and the groove 81 connects the inlet port 73 sprlng lock to hold thespring in with the groove 83, while the groove 80 con 7 lower end of the cylinder which registers with, and connects the lower chamber at all times with, the annular groove 83. In like manner, the upper chamber of the cylinder is connected at all times with the groove 82 through a port 86 (Figs. 7 and 9), and through duct 87,-which'is'formed by a tube -88passing upward along the outside of the cylinder and terminating in an open upper end 89 (Fig. 10). The upper end of the duct 87 opens into the upper chamber im mediately below thecap through a lateral port 90. In Fig. 11' it will be observed that instead of using the port 90, the duct 87 may continue on through a duct or passage 87 formed in the cap. This latter duct connects the upper end 89 of the duct 87 with the upper end of the tube 67, and in this manner communication is established with the upper chamber of the cylinder through .lar requirements and conditions.

the lower end of the tube 67, for purposes tovbe more fully explained hereinafter.

The liquid may be fed to themeasuring and filling units at whatever pressure may be, found to be best adaptable to the particu- Other things being the same, the speed at which the cans are filled depends upon the degree of pressure applied to the liquid. In

the case of condensed milk, I find in pracintake port through the passages of the reverser, and the duct or passage to the upper chamber'of. the mechanism, as above explained, and being under pressure will gradually fill the upper chamber with an exact predetermined'quantity of liquid by forcing the movable partition 65 downwardly'to the bottom of the cylinder. As the movable partition moves downwardly,-

it gradually and proportionately decreases the capacity of the lower chamber and forces the previously measured quantity of liquid in the lower chamber through several ports and assa' es and into the can through nozzle A ter the pre-measured quantity of milk froin'the lower chamber has thus been injected or charged into the can, the movable partition positively closes the outlet port 85 at the lower end of its stroke and no milk can pass through the mechanism until the direction .of flow is reversed by giving the reversing member 74 a half turn.

a When the reverser is thus rotated, it conher "and simultaneously forcing the 'pre-' nects the inlet port 73 directly with the lower chamber of the cylinder and connects the upper chamber of the cylinder with the outlet port 84 and nozzle N. This causes the movable partition 65 to rise 'in the cylinder, thus gradually filling the lower chammeasured quantity of milk from the upper chamber into the next or succeeding can which has been connected with the nozzle. In the structure shown in Fig. 6 the mov-' able partition 65 does not actually cover the upper port 90 as it does the lower port 85, but its movement is positively stopped by the gage 66, which has identically the same effect as though it did actually close the port 90. This-isobvious, for the reason that although there is a quantity of liquid still left in the upper chamber above and in the movable partition itself, the gage rod 66 positively prevents anypressure whatever formed with the being applied to this remaining quantity, and in consequence it willnot flow through the port 90. Thus the quantity of liquid which the upper chamber pre-measures is represented by the difference between the quantity of liquid in the upper chamber when the movable partition 65 is in its lowest position and that remaining in the upper chamber after said movable partition has reached its upper limit of movement against the gage rod. In Fig. 11, however, I have arranged the structure so that the movable partition positively and. directly closes the upper port as it does the lower port, which structure I adoptwhen the nature of the particular liquid renders it ad- Visable to do so. In this structure it will be observed that the lower open end 99 of the tube 67 represents the port 90, and is positioned so that the movable partition 65 will cover and positively close said end. It will be remembered from the preceding description that the tube 67 is longitudinally adjustable, hence it serves the same purpose as the gage rod 66, so far as regulation is concerned. As before intimated, I construct these measuring and filling mechanisms in this manner so that they may be adjusted to the filling of two different sizes of cans or vessels. In Fig. 6 this may be 9 accomplished in a simple manner, such as by means of a central upstanding stud or projection ;100, and the gage rod 66. The upstanding studlOOis preferably integrally I floating valve 65, and the length or height of this stud exactly represents the difi'erence between the two sizes of cans to be filled. On the lower end of the. gage rod I form a lateral extension or foot 101 which, by the rotation of the gage 105 as previously described, may be interposed in the path of the stud 100 and thus. stop the movable partition in a lower position. Obviously a lesser quantity of milk or liquid will be forced from the upper chamber and a proportionately lesser amount will enter the lower chamber. In this manner a smaller can may be filled. In the structure shown in Fig. 11, the same results may be accomplished by making the tube 67 in two sections, the lower section 67 of which may be removable and may represent the exact difference in the two sizes of cans. In this figure I have shown the section 67 in positionand the mechanism thereby adjusted for the smaller can. By removing said section, however, it is obvious that the mechanism may be instantly set or adjusted to filllarge size cans. For the sake of simplicity, I have illustrated the mechanism adjustable to two sizes of cans only, but it is clearly obvious that the range of sizes may be increased by providing, in the structure of Fig. 7, a corresponding number of different length studs '100, or, in the structure of Fig.

As I havepreviously described, the cansare successive y elevated to the filling level 17 shortly after leaving the feeding chute. The elevating of the cans in this manner causes the nozzle tips 38 (Figs. 1, 2, 3, 4 and 12) to enter the filling openings 0 in the cans. In order to avoid lossof time in the process of filling, I arrange the parts so that the reverser '74 will be .actuated shortly after the cans rise to their filling position, and the nozzles enter them. I prefer that the actuation of this reverser be controlled by the movement of the cans themselves, and for this reason I pivot an arm 105 upon the stationary standard 13' (Figs. 1, 2 and 3). This arm has a hooked end 106, and it also has an angularly disposed V-shaped cam extension 107 disposed in such manner'asto ride upon the heads or tops of the cans asthey are moved in their annular path. These parts are so proportioned that when the cam extension 107 rides up on the moving cans, it will project the hooked end 106 of the arminto the path of snubs 108 formed on the projecting end portions 75 of the reversers and successively actuate said reversers. I have so proportioned the parts of the machine shown in the drawings that the filling process will occupy about the time consumed bythe rotary conveyer B in making about three-fourths of a revolution. As before intimated, the movable partitions 65 are arranged to close the upper or lower ports of their filling mechanisms, as the case may be, shortly before the cans reach the incline 18,pos itioned at the point H. The filling they maybe actuated at any point in theof the cans will be thus completed and in.

readiness to be disconnected from thenozzles when they reach the incline 18. Since the reversing members do not close and open the ports in the cylinder but instead merely control the direction of the flow of the liquid through the mechanisms, it is obvious that revolution of the rotary conveyer B. For this reasonand for the sake ofsimplicity,

I'prefer to arrangethem that each half or flow-reversing turn thereof will be. ac

complished'in two steps of a quarter turn For this reason I provide a projec-- I like the snubs 108, are arranged in. alinement but are disposed at right angles to the snubs tion or lug 1.10 on the guard standard 27 (Fig. 4). This is positioned to be engaged by two other snubs 108 also formed on each reversing member 74. The two snubs 108 1018 (Figs. 6, 8 and 9). They also lie in a plane offset with respect to the plane of the snubs 108, so thatv the snubs 108 only engage the automatic actuating lever 105 and the snubs 108 onl engage the lug 110. The advantage of 0 setting the two sets of snubs in this manner lies in the fact that the actuating member'105 will always complete the reversing half turn ofthe member 74:

shortly after the cans enter the machine,

thus insuring against the possibility of dead centering the reversers at the point where the cans are connected tothe nozzles.

The liauid may be supplied to the measuring an filling units in any manner found to be most convenient and satisfactory ac-- clined and connected to the ends of theshort inlet pipes 72 of the measuring and 4 filling units. These pipes. are preferably of the same diameter as the pipes 72, and

they may be connected therewith by means of short pieces of rubber or flexible tubing 116, slipped over the adjacent ends of the pipes. This arrangement enables any of the measuring and filling units to be disconnected independently of the remaining mechanisms by simply sliding the tube along either the tube 72 or the supply pipe 115 in order to separate the connected en vantage that both the supply pipes 115 and the inlet. tubes"72"of the mechanisms are readily" accessible for flushing and cleaning purposes. The central supply manifold is sufiiciently large to properly divide the main stream of liquid from the supply pipe 115 into the various individual streams ,for the individual supply pipes 115.

This screening member may be for the sake of strength and rigidity mounted in a ring shaped member-or frame- (is 1 thereof. This arrangement also has the ad-- 120. as clearly shown inthe -.drawings. In I order that the main supply pipe mav remain stationary while the manifold rd- In a machine of this character designed to fill cans or other vessels which are afterward sealed by soldering or sealing the openings thereof, it is quite essential that none of the liquid slop over onto the tops of the cans or drip thereon from the filling nozzles, since this would make the sealing difiicult. In this machine no trouble is experienced on this account in connection with the liquid charged into the cans from the lower chambers of the measuring and filling mechanisms, for the reason that as previously explained, the floating member 65 actually covers-the port 85 at the end of its down stroke. In the case of liquid charged into the cans from the upper chamber or compartment, however, there is some likelihood in practice of a drop forming at the end of the nozzle after the floating valve has been stopped on its up stroke by the gage 66 on account of the fact that an extremely small quantity of liquid oozes past the floating valve member 65 from the lowercom'partment and enters the upper compartment. The effect of this slight leakage in forming a last drop at the nozzle exits only in the mechanism shown inFigs. 6, 7, 8 and 10,

the reason being that the floating member does not actually cover the port 90. In order, therefore, to avoid the possibility of a last drop accumulating at the nozzle, I provide a mechanism which imparts .a slight .hammer blow, so to speak, tothis remaining column of liquid in the passagesleading from the upper compartment, theielfect being to knock off the drop at the nozzle.

It is manifest that this condition does not.

0 'exist in the structure shown in Fig. 11 since the floating member' as before explained, actually covers the port 99 .atthe lower end of tube 67. Referring to Figs. '6, 7, 8 and 10,

it will be remembered that the upper end of the tube 88 is open. The cap member 51 has an integral oflset portion 126 overhanging the open end of.-the tube 88. This ofiset portion carries a small resilient cap 127, which covers the end of the tube. This cap 127- has a small plug 127 which sets into a vertical bore or hearing in the oilset portion,

126 and above this plug is asmall hammer rod128 which is normally held against the end of the plu'g'by spring member 130. This spring member is maintained in position by sudden hammer blows cause the forming or ments and simultaneously directing the liqmeans of a hollow screw cap 131, shown more particularly in Fig. 10. The hammer 128 passes upward through this screw cap and carries a laterally extending arm 132, by which it may be raised against the tension of its spring. Upstanding from the frame or. bench A of the machine is a standard 135, the upper end portion 136 of which is formed, as shown more clearly in Fig. 1, to overhang the measuring and filling mechanisms. A cam or incline 137 is formed on this upper end portion of the standard, and

is positioned in the path of the arms 132 in such manner that as the mechanisms pass 137 and then ride ofi' suddenly. -As they ride off the cam 137 their springs 130 impart a sudden blow to the columns of liquid in the ducts 87 and connecting passages. These formed drops to leave the nozzle tips. The cam 137 on the standard 135 is so positioned that the knocking oil of the excess drop occurs just after the floating member 65 has been stopped by the gage rod 66 and before 90 the cans are disconnected firom the nozzles.
